CETS (573881) writes "The National Center for Education Evaluation and Regional Assistance produced this major study of the effectiveness of education technology. Mandated by Congress, the report uses scientifically based research methods and control groups to focus on the impact of technology on student academic achievement. The main findings of the study are:
Test scores were not significantly higher in classrooms using the reading and mathematics software products than those in control classrooms.
There was substantial variation between schools regarding the effects on student achievement. Although the study collected data on many school and classroom characteristics, only two characteristics were related to the variation in reading achievement. For first grade, effects were larger in schools that had smaller student-teacher ratios (a measure of class size). For fourth grade, effects were larger when treatment teachers reported higher levels of use of the study product.
